WORKING SCHEDULE OR INDICATING GUIDE.

Application filed .nmezr,

T 0 all whom it-may concern:

. Be it. known that I, ROBERT H. HARRIsON, a citizen of the'UnitedStates, residing at Raleigh, in the county of ake and State of NorthCarolina, have invented certain new and useful Improvements in WVorkingSchedules or Indicating Guides, of which the following is aspecification.

This invention relates to certain improvements in working schedules orindicating guides, to facilitate in an efficient and accurate manner thecarrying out of a predetermined series of operations, at predeterminedperiods of time, the device beingpa-rticularlyv well adapted for use inconnection with laundry work. e

Generally stated the improved device comprises a bar, strip, or thelike, provided with a graduated series of markings representing,preferably, intervals of time in units of ten minutes each, sufficientin number to cover a period of twelve hours. Cooperating with this firstmentioned baror strip is a second like member also i-provided withcorrespondinggraduations, .the twowmembers being slida'bly securedtogether and operating in-a manner similar to a. slide rule. Thegraduations on the first mentioned baror strip are-represented. bynumbers indicating the different intervals of time,,but the graduationson the second cooperating member are not so numbered, said graduationsbeing adapted to cooperate with changeable indicia, representing thevarious steps of the contemplated process, all combining to carry outthe desired purpose, in a manner to be hereinafter more fully described.

The preferred embodiment of the invention is illustrated in perspective,in the accompanying drawing, parts being broken away to properly showthe essential features of the invention.

Referring to the drawing in detail the main portion of the devicecomprises'a bar or strip 1 of any desired mate ial, prefer ably about 36inches long and provided on its face with a series of graduations,representing in the present instance, periods of time in units of tenminutes each, ranging for example, from 6 oclock to 6 oclock, covering aperiod of twelve hours. These graduations are marked by numerals asindicated at 3, in consecutive order as shown and in the periods stated.

Cooperating with the bar 1 is a complementary bar 4, slidably connectedthereto by 1923. Serial No. 648,040;

to the graduations 2 of the bar 1, the bar 4 is likewisemarked,.themarkings on both bars being arranged along adjacent edges forobvious reasons.

U-shaped yokes or straps 5. Corresponding Formed in the upper faceof'the sliding;

ception of indicia carrying tags orstrips 7,

the indicia thereon representing the various steps of the processorseries of operations to be performed, said strips 7 beingadapted to beshifted or moved with respect to each other as required or called for inaccordance with the desired operation.

- As hereinbefore stated the present device has beendesignedparticularly for the use in laundry establishments and theoperation thereof will be explained in connection with this class'ofwork, wherein it is desired to carry on certain steps for a certainlength of time with certain intervals. Assuming for example that thefollowing formula or schedule is used, cold rinse 10 minutes,- firstsuds minutes, second suds 20 minutes, bleached 20 minutes,yfirst rinseten minutes, second rinse 10 minutes, sour-:10 minutes, blue tenminutes, the indicia -will be arranged on the bar 4 as shown in thedrawing, where said graduations indicate five minute intervals. Thecorresponding graduations on bar 1 are also arranged in 5 minuteintervals, but it is only necessary to mark every other one or each 10minute period of time.

If the operation is to begin at 1.30, the bar 4 is moved along until theindicia for the first operation is opposite the graduation 1.30 on thebar 1, whereupon the time for each succeeding step will be representedon bar 1 as shown. Of course if the operation is to begin at some othertime, it is only necessary to slide the bar 4 along bar 1 until theinitial step is opposite the desired period of time, the time for thefollowing steps being indicated in a manner as hereinbefore described.

From the foregoing it will be apparent that various predeterminedformulas or steps of a certain process or operation can be arranged onthe bar 4 in any sequence or order as desired, properly spaced to givethe required interval of time between each step, so that when said bar 4is associated with the bar 1, and by placing'the initial step oppositethe indicated "time for beginning the operation, the time forchang ingor performing each successive step of the process will be automaticallyindicated on the bar 1.

Although the invention has been illustrated and described in connectionwith a laundry or washing operation, it is not to be so: limited, as itwill of course be perfectly obviouspthat the same is applicable in itsuse to any'operation involving-a series of steps of the like nature. hatI claim is; 1. In a working guide or schedule, the combination with amain portion, of a sup plemental portion associated therewith,graduations on said main portion, means for interchangeably arangingindicia on said supplemental portion in spaced relation in the'desiredcombination, said spacings following a unit of measurement according tothe graduations' on said main portion and means for obtaining acooperatingreading between said portions. Y i

2. In a working guide or schedule, the combination with a main portion,of a supplemental portion associated therewith,

ing readingbetween said portions.

graduations on said main portion,'-indicia carrying strips supportedupon said supplemental portions, means for interchangeably arrangingsaid strips'there'on in spaced relation in the desired combinations,said spac ings'following a' unit of measurement accordingvto thegraduations-on saidmain portion. and means for obtaining a coopera t- 3.In a working guide or schedule, the combination with a main portion,of-a supplemental portion associated therewith,

- thereby.

graduations on said main portion, corresponding graduations on saidsupplemental portion, lndicia carrying strips,

.means for securing said strips to the supplemental portions in spacedrelation in the desired combinations, and means for obtaining acooperating reading between said portions.

4:. In a working guide or schedule, the combination with a main portion,of a supplemental portion associated therewith, graduations on said'mainportion, corresponding graduations on said supplemental portion, holesformed in the supplemental portion opposite each graduation, indiciacarrying strips, pins passing through the strips into said holes forsecuring the strips to the supplemental portion in spaced relation inthe desired combination, and means for obtaining a cooperating readingbetween said portions.

In a working guide or schedule, the combination with a main bar or rod,of

a supplemental bar associated therewith,

graduations on said main bar, numerals representing regular periods oftime designating said graduatlons, corresponding graduations 'on'saidsupplemental bar, holes 7 formed in the supplemental bar opposite eachof said latter graduations', indicia carrying strips, pins passingthrough the strips into said holes for securing the strips to theSupplemental bar in spaced relation in the desired combination, andmeans for causing a close sliding engagement between said bars to obtaina cooperating reading In: testimony whereof I afiix my signature.
